Specification of Letters Patent.

Patented April 10, 1906.

Application filed September '7J 1904. Serial No. 223,621.

To a/ZZ whom it may concern/f Be it known that I, MAURICE FRANKHUToHIsoN, a citizen of the United States, residing at Floris, in thecounty of Fairfax and State of Virginia, have invented certain new anduseful Improvements in Locks, of which the following is a full, clear,and exact specification.

This invention relates to that class of devices designed to prevent theswinging open 0f the doors of stables, outhouses, cupboards, 6to.,commonly controlled by buttons or turn-buttons,J and also to provide inthe same device a substantial lock for said doors.

In many instances it is desirable and even necessary to positively lockthe door ordinarily held closed by a turn-button, and this 1s usuallyaccomplished by the employment of an independent lock to be used when itis desired that free entrance through the door shallll not be had-as forinstance7 during the nig t.

One object of my invention is to provide a turn-button that may be setto turn freely to permit opening of a door or may be locked to hold thedoor in a closed position until a proper key is used to unlock thebutton and pernnt its movement to release the door.

' Another obj ect of the invention is to adapt such door-buttons forcontrolling the opening of sliding and double-swing doors.

Another object of the invention is to produce an inexpensive deviceembodying a button and a lock (which T shall hereinafter term abutton-lock) wherein the device may be used as a mere button to be movedat will to release a door or as a lock requiring the use of a key tomove it from in front of the guarded door.

A further object of the invention is to produce a button-lock havingidentical tumblers formed by a single die and so constructed andarranged with the button body or casing as to be operated as a wholeonly by a key having properly-cut wards corresponding to the number oftumblers used, thus providing for many combinations of the tumblers.

With these and other objects in view the invention consists in thematters to be hereinafter described in detail and then particularly setforth in the claims at the end of this description.

Referring to the accompanying drawings,

forming a part of this specification, and in which similar characters ofreference are used to indicate corresponding parts in each of theseveral views, Figure 1 is a view, partly in section, of my improvementattached to the side of a building. Fig. 2 is a cross-section on theline 2 2 of Fig. l. Fig. 3 is a perspective view of the back or anchorplate removed. Fig. 4 is a view of a modification for use ondouble-swing or sliding doors. Fig. 5 is -a sectional view on the line 55 of Fig. 4, and Fig. 6 is a view of one form of key that may be used inoperating the lock.

My button-lock embodies a plate A to be secured to a door-j amb or toone of a pair of sliding doors, and which I shall hereinafter term theanchor-plate, to which is rigidly attached or formed therewith toproject at right angles therefrom a tubular post A', having alongitudinal slot a. Said post A serves as the journal or pivot on whichthe button is to turn to hold a door or release it.

The button proper comprises an elongated frame or body B, pivoted atabout its center on the tubular post A and provided on its inner sidefacing the anchor-plate with a recess b, extending from one end of theframe or body B to include the post, as clearly shown, a keyhole or slotb being formed in one edge wall of the body about midway of the recess.Projecting into the recess b, near that end remote from the post A,is apivot-pin b2, on which is fulcrumed a plurality of tumblers C, (four inthe instance shown,) identical in coniiguration, being the product of asingle die, each provided at one end with a projection or toe c, adaptedto engage the slot a of the post A', and at the other end with a seriesof perforations c', gaged to fit and turn freely upon the pivot-pin b2,projecting across the recess b. From this construction it will be seenthat many combinations or changes may be made in mounting the tumblersto accord with the wards of a key K to be used in lifting the toes c ofthe tumblers from the slot a of the slotted post A to permit therotation of the frame or body B thereon.

The anchor-plate A is so shaped and proportioned that the screws, bolts,or rivets attaching it to a door or door-j amb or other object will beconcealed and inaccessible when the button-lock is in locked position,thus preventing tampering; but when the button- IOO lock is turned torelease a door the screws or other fastenings are exposed tomanipulation for insertion or removal.

To prevent the button end of the buttonlock from being accidentallymoved when used simply as a button from in front of the door beingguarded, there may be provided between the back plate B of the body B aleaf-spring shaped to engage a projection or stud on the anchor-plate.Other means, if desired, may also be provided for this purpose.

From the construction so far described it will be apparent that when thebutton-lock is in the position shown in Fig. 1 the door 1 will be heldclosed, On releasing the tumblers from the slotted post the body of thelock may be turned on its pivot (post A) and moved from in front of thedoor 1, thus releasing it. When shut, on further rotating the frame B onits pivot its other or non-locking end will be moved across the door;but as the toes of the tumblers C now travel in contact with theunbroken surface of the tubular post A the movement thereof ispractically unrestricted and may be moved to guard or release the door.

An obvious modification of my button-lock is illustrated in Figs. 4 and5, wherein it is shown as adapted for double-swing doors and for slidingdoors. In these figures the frame or lock A is shown as provided at eachend with a hook B2 B3, adapted to engage a staple or keeper D on themoving door. The operation is the same as already described, except thatthe hooks B2 B3, enga ing the keeper D, will prevent opening of t euarded door, whether it be a swing-door, a s iding door, or adouble-swing door, as will be apparent. In the event of securing thekeeper D to a door 1 for engagement witha hook B2 or B3 of thebutton-lock, as shown, it will be expedient to so construct the hooks asto avoid possibility of tampering with the securing-screws of thekeepers while the hooks are inlocked or guarding position. To this end Iprefer to shape the hooked ends of Ithe body as shown in Figs. 4 and 5,wherein an integral hood B4 overhangs the engaging tongue ofthe button,said hood terminating at its outer end in a guard b4, overlying theouter fastening-screw of the keeper. the keeper will of course beconcealed and protected by the body of the button-lock. In ordinaryuse-say on a stable or pantrydoorthe anchor-plate will be xed and theslot of the pivot-pin will be at the upper side thereof. Under theseconditions it is not necessary that a spring or springs be used to forcethe tumblers into engagement with the slot of the pivot-post A',although I may so use the same 5 but in cases where my button-lock is tobe used on portable articles, as shipping cans, cases or boxes, whichare `liable to be turned on one side, or upside down, so that The innerfastening-screw of the slot of the post is not uppermost and thetumblers cannot engage it by gravity, a spring or springs will beessential. To this end I have provided. springs E, secured at one endwithin the recess of the frame or body and bearing at the free end onthe free ends of the tumblers, as shown. As herein shown, theanchor-plate A and body B are secured together by means of a bolt orrivet F, passing through the tubular post and swaged up or headed at theinner end thereof, but it will be understood that the post itself maybethe connecting means, and it is also obvious that the post may besolid and provided with a longitudinal groove or channel to receive thetoes of the tumblers, also that the slot of the post need not extendlongitudinally the entire length thereof, but a slot or openingsprovided to receive the locking ends of the various tumblers.

In the hooked form shown in Figs. 4 and 5 my device is well adapted foruse as a hasplock, and so used the anchor-plate may be dispensed withand the post A be secured to the leaf of the hasp, as will be wellunderstood.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. A lock embodying the functions of a lock and of a turn-button,comprising an anchor-plate having a grooved post, and a recessed buttonpivoted between its ends on said post and provided with tumblers forautomatically engaging the groove of the post.
